Lets see the other way of data transfer between external environment and the Flex using AMFPHP. Important points regarding AmfPhp ?

1. AMF stands for Action Message Format.

2. It is a binary file that is used to represent a serialized ActionScript object.

3. It was designed to serialize and deserialize quickly.

4. AMF 3 for ActionScript 3 and AMF 0 is for (AS1 & AS2).

5. AMF 3 supports sending int and uint objects.

6. AMFPHP automatically converts ActionScript data types to PHP data types.

Lets have an example amfPhp and Flex 4.5 connection and data exchange between them.
Step 1 : Install AmfPhp in your wamp server :

amfphp_in_root_directory_www

Step 2 : If installed properly check the gateway.php . It should look like this :

amfphp_gateway_look

Step 3 : Check the browser . It should look like this :

amfphp_in_browser_look

Step 4 : Write a class for php. Here I am writting a dummy data as return which is containing Employee detail.

[xml]

fname = “Aava”;

$emp->lname = “Anjan”;

$emp->age = 28;

return $emp;

}

}

?>

[/xml]

One more class is refrencing the employee. Further we will expand it in our next example .

[xml]

[/xml]
Step 4 : Check the browser and Click on ‘call’ button you will get result like this :

result_on_call

Step 5 : Now Create a new Flex Project where we will see the employee detail by connecting
with AmfPhp . Here are the codes :

[xml]

<?xml version=”1.0″ encoding=”utf-8″?>
<s:Application xmlns:fx=”http://ns.adobe.com/mxml/2009″
xmlns:s=”library://ns.adobe.com/flex/spark”
xmlns:mx=”library://ns.adobe.com/flex/mx” minWidth=”955″ minHeight=”600″>
<fx:Declarations>
<!– Place non-visual elements (e.g., services, value objects) here –>
</fx:Declarations>
<fx:Script>
<![CDATA[
import com.RemotingServiceManager;
import flash.events.MouseEvent;
private var _rc:RemotingServiceManager = new RemotingServiceManager()
protected function search_btn_clickHandler(event:MouseEvent):void{
_rc.getEmployeeDetail();
}
]]>
</fx:Script>
<s:Button id=”search_btn” x=”158″ y=”141″ width=”189″ height=”34″ label=”Click to Get Employee Detail”
click=”search_btn_clickHandler(event)”/>
<s:Label x=”150″ y=”95″ color=”#570404″ fontSize=”17″ text=”Example of Flex and AmfPhp”/>
</s:Application>

[/xml]

Step 6 : Run and Click on the Search button . It will show you result :

flex_result
